[counterintuitive] more few-shot examples always better

Use 3-5 highly diverse, high-quality few-shot examples rather than dozens. If you need more, switch to fine-tuning, as excessive few-shot examples cause attention dilution and overfitting to the specific example format.

Journey Context:
Developers add 20\+ few-shot examples to prompts, assuming more examples equals better generalization. In-context learning has severely diminishing returns. Too many examples eat up the context window, increase latency, and cause the model to overfit to the exact phrasing of the examples rather than the underlying pattern, degrading performance on edge cases. Quality and diversity of examples matter vastly more than quantity.
